FI report using 'Report painter'

Hi All,

I am working on trial balance and created the BADI 'G_SET_FORMULA_EXIT' with the filter 'U001' saved and activated. I am now trying to create the variable with FORMULA '#U001' but i getting the following error:

Variable name '#U001' not possible, please check syntax

Message no. GS740

I am not sure what part i am missing. Can anyone please help me out with this? Any docs/Link are appreciated.

Thanks,

Karun
